ownership:I own this lens
compared to:Mino 100-300/4.5-5.6 APO
Mino 200/2.8 APO HS with 1.4x APO TC
price paid:$350??
positive:Very decent sharpness
Extremely solid build (gets a 4 due to Zen finish, which is getting tacky)
Fantastic focus mechanism, despite MF/AF control ring
Fast positive AF performance at distance, quite decent macro AF
Solid performance at MFD and at infinity
Very close to true APO performance
Smooth bokeh
negative:Zen finish *still* sux
MF/AF clutch is awkward
Dull colors and diminished contrast compared to Minolta legacy glass
So-so performance with Sigma 1.4x teleconverter (though it isn't a specifically matched one, so I expected this)
comment:A very decent compromise lens for those who don't want to shell out for a Minolta G telephoto, or anyone who wants a longer working distance than the Minolta or Sony macro lenses offer.

Both compared Minolta lenses have more vibrant color and more apparent contrast than this optic, the 200/2.8 is a sharper more dimensional looking lens even with the 1.4x TC attached, while the 100-300APO is almost as sharp at 300mm, but has brighter colors.

I find that since getting the two Minolta lenses I compared it with, the Sigma 300 macro really doesn't get much use anymore :( Still, I'd certainly recommend it to anyone looking to get an affordable long telephoto for daylight use, or who wants to do macro work at longer working distances.

I didn't list the other zoom lenses I own that will go to 300mm, since the Sigma is sharper and has better aberration control than all of them.
